General Notes On Using The Charger - GRAUPNER ULTRA QUICK 70 Operating Manual

Lead-acid batteries are not capable of being charged at high currents. Never exceed the maximum charge rate stated by the battery manufacturer.
Protect batteries from vibration, and do not subject them to mechanical stress or shock.
Batteries can generate explosive gas (hydrogen) when on charge and when being discharged, so it is important to provide good ventilation.
Do not allow batteries to come into contact with water - explosion hazard!
Never short-circuit battery contacts - explosion hazard!
Batteries can explode or burn, if they overheat. We suggest to use a LiPo-security hard case Order-No. 8370 or 8371 with all Li-battery
types and with NiCd und NiMH-batteries for charging.
Do not open battery cells - corrosion hazard.
It is best to „balance", or even up the cells in Ni-Cd and Ni-MH battery packs by fi rst discharging all the cells separately and then charging up the
pack. Batteries can be discharged cell-by-cell using a charger.
Please don't be surprised if your batteries are not as willing to accept charge in winter as in summer. The ability of a cold cell to accept and store
charge is much lower than that of a warm one.
Battery disposal: exhausted batteries are not ordinary household waste, and you must not dispose of them in the domestic rubbish. The retail outlet
where you purchase your batteries should have a battery recycling container for proper disposal. Trade outlets are obliged by law to accept exhausted
batteries for disposal.

5. General notes on using the charger

Charging batteries
When a battery is charged, a particular quantity of electrical energy is fed into it. The charge quantity is calculated by multiplying charge current
by charge time. The maximum permissible charge current varies according to the battery type, and can be found in the information provided by
the battery manufacturer. It is only permissible to charge batteries at rates higher than the standard (slow) current if they are expressly stated
to be rapid-charge capable. The STANDARD CHARGE CURRENT is 1/10 (one tenth) of the cells' nominal capacity (e.g. for a 1.7 Ah pack the
standard charge current is 170 mA.
